Some cloudflare cons: Cloudflare makes websites unavailable if you use services like unblock-us.com (see below) High amount of 404 I get from cloudflare when browsing /r/pics makes me wonder who is to blame. Cloudflare is short on locations. Cloudfront is cheaper if you use SSL. ============ ➜ ~ dig cloudflare.com ; <<>> DiG 9.8.3-P1 <<>> cloudflare.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 3675 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;cloudflare.com.

Even with Unblock-Us I can reach CloudFlare just fine here (Berlin, Germany): ; <<>> DiG 9.8.3-P1 <<>> @208.122.23.22 cloudflare.com ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 12445 ;; flags: qr rd ra; QUERY: 1, ANSWER: 5, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;cloudflare.com.

  It looks like location influences results. Tried again at home , same results. Tried on different ec2 instances: fine on us-east, no go on sa-east-1.

>Cloudflare makes websites unavailable if you use services like unblock-us.com No they don't. CloudFlare just has a security mechanism where known bad or risky IPs are presented with a captcha. However on sites with "max" security, I believe it simply blocks them entirely.
